specification forming pta of Letters Patent No. 112,665, dated March 14, Ien.

I, AUGUST WNUCK, ,of cincinnati, Eemnton county, Ohio,zhaveinvented an Improved Carriage-Brake, of `which the following is a specication:` I

Nature and Objects of thc Intention. This invention consists in connecting the rearaxle of a carriage to the body by means of a radius-rod, whichrod not only maintains y the bodyand axleat" a certain fixed distance from one another,"butit also serves as a support to` the braking mechanism, the principal member of whiclfis a bar having a shoe or rubber ,at its front end,said bar beingadapt d'to traverse the radius-rod so as to bring the brake into action by means of an arrangement of forked levers, ropes, and pulleys, which will be hereafter fully described.

i Description `of the Accompanying Drawing.

` General Description.

A represents the body of a.coach,'carriage, or other four-wheeled vehicle. B is the front axle. C is the rear axle, and D D' E E are, respectively, `the front and rear wheels of the same. i

Firmly attached to the body A, and at a suitable distance in front of the rear axle, G, is a bar, F, to which are secured the forward ends of the radius-rods G G'. The rear ends of these rods aretpivoted to clips c c', which are fastened to the axle C.

Placed outside ofthe radius-rods G G', and parallel therewith, are bars H H',whose forward ends carry the shoes or rubbers I I'. In order to permit of said bars traversing the rods G G',so as to bring the rubbers into action, they are providedwith guides J J' and studs K K', which latter occupy slots g in the rods-G G'. The studs K K are furnished with nuts k le'.

Projecting inwardly from the rods G G' are lugs g', which serve as fulcrums forthe levers L L', having forked extremities l l', which embrace the. bars H II', and are attached thereto by bolts M.

The lever L', which is somewhat longer th an the one L, has attached to its free end a rope or `light chain, O, which communicates with the brake-lever l?, the latter being located in such a position as to be convenient to` the driver of the vehicle. I

A proper direction is given to the rope O by means of the rollers or pulleys It. The two levers L L' are united by alink, S.

T is a spring, which retracts the levers L L' so as to throw the rubbers out of contact with the peripheries of the wheels E'.

Operation.

In the'riormal or non-effective position of theapparatus the rubbers I I' are maintained A out of contact with the wheels E E' by the action of fthe spring T, and whenever it is desired to stop the carriage'. the driver has only to press his foot against the lever P and force it into the position indicated by dotted lines in Fig. 1, which act brings said rubbers into operation through the medium of rope O, levers L L' Z l', and sliding'bars H H'. The

carriage having been stopped, the moment the driver removes his foot from the lever l? the spring T instantly restores the brakes to their non-eective position.

The braking apparatus, being mounted upon the radius-rods G G', can be operated at any moment, as the action of said rods maintains the carriage-body and rear -axle at a certain iixed distance apart, and no amount of oscillaltion can change the relation existing between The bar F can be omitted, and the front ends of the radius-rods can be bolted to the sides of the carriage. The clips c c' can also be dispensed with, and the rear ends of the rods G G can be arranged so as to embrace the axle O.

Olips or slides may be substituted for bolts k k.

Claim.

I claim as my invention- In combination, substantially as described, With the sliding bars H H J J', rubbers I I',

levers L L', or their equivalent operating medium O l? R, the radius-rods G G', to be hinged or pivoted to the body of the vehicle and to its rear axle, as and for the purpose explained.

In testimony` of which invention I hereunto set my hand.

AUGUST WNUOK.
